2 Claims. (Cl. 240-10.6)

The present invention relates to improvements in n 1ght lamps, and moreparticularly to a night lamp provided with a luminous means forindicating the posltion of the lamp at night time.

An object of the present inventlon is to provide an improved electriccontact actuating means whereby the lamp bulb may be illuminated.

The invention also comprises novel details of construction and novelcombinations and arrangements of parts which will more fully appear inthe course of the following description.

Various other objects and advantages Wlll be apparent from the detaileddescription to follow, wherein parts are at times identified by specificnames for convenience, but such nomenclature is intended to be asgeneric in its application to analogous parts as the prior art willpermit.

The best form in which I have contemplated applying my invention isillustrated in the accompanying drawings, wherein:

Figure 1 is a vertical sectional view of the present 1nvention with theelectrical circuit closed;

Figure 2 is a horizontal transverse sectional view taken substantiallyalong the plane of line 2-2 of Figure 1; and

Figure 3 is a vertical transverse sectional view taken substantiallyalong the plane of line 33 of Figure 1.

Referring more particularly to the drawings, wherein like numeralsdesignate like parts throughout, numeral designates generally the basemounting means, numeral 12 designates generally the bulb socket means,numeral 14 designates generally the dry cell tubular housing and camactuating means, and numeral 16 designates generally the luminous meansand bulb arrangement of the present invention.

The base supporting means 10 includes a hollow housing having apreselected ornamental design for its upstanding portion 18, and a flatbase wall 20 upon which the invention is rested, the base means 10 beinghollow and provided with an internally threaded and apertured upperportion 22. The base wall 20 is provided with a stop projection 24, fora purpose to be hereinafter described.

The dry cell 26 is mounted within a tubular housing 28 which is fixedlysecured to the base wall 20 at a central portion thereof and is providedwith transversely extending apertures 30 in axial alignment with eachother and offset from the center line of the tubular housing.

Slidably mounted on the base wall 20 and engaged with the apertures 30of the tubular housing 28 is a cam actuating slide element 32. The camactuating element 32 is provided with an elongated wire 34 extendingtherefrom and provided with a button 36 at its outer end, wherebyreciprocation of the cam actuating element 32 on the exterior of thebase mounting means 10 is made possible. The cam actuating element 32 isprovided with a surface 38 which may be inclined in either directionwhereby reciprocation of the cam actuating element may be employed forvertical reciprocation of the dry cell 26.

An electrical conducting element 40 is positioned with its upper endembedded inthe socket-receiving portion 22 and with its lower endconnected to a contact button 42 which is in sliding engagement with theinclined surface 38 of the cam actuating element 32.

An externally threaded tubular sleeve 44 is positioned Within thesocket-receiving portion 22 of the base means 10. The lower end of thesleeve 44 is provided with a contact element 46 which is adapted to beconnected to 2,695,355 Patented Mir-2.3, 1954 the contact element .48atthe upper. end f he electric l conducting element 4.0 when thesleevelsl is fully threade into the aperture 22. .A reflector 5.0 ismounte Within the sleeve 44 bymeans of its periphery 52 engaged in thecounterbore 54.0f the sleeve .44. The reflector 50 is. provided .with asocket. portion 5.6 in which a lamp bulb 58 may be threadablypositioned, and an electrical conductor 60 connects the socket 56 withthe contact button 46.

The luminous lamp structure 16 includes a transparent bulb portion 62,which may be formed of glass or plastic that is translucent, which hasits lower end fixedly mounted within a recessed portion of the sleeve44. The upper end of the bulb portion 62 is provided with a blister-likesemispherical extension 64 in which is positioned a crimped reflector 66whereby the light rays from the lamp bulb 58 may be diffused anddeflected.

Artificial flowers 68 are mounted with the bases of their stems fixed inthe sleeve 44 and are upwardly standing within the bulb portion 62. Theartificial flowers 68 may be formed from glass or metal, and, ifdesired, means other than flowers may be employed. The artificialflowers 68 are covered with a luminous material which glows in thedarkness.

From the foregoing description, taken in conjunction with the drawings,it is believed that the operation of the present invention will bereadily obvious to one skilled in the art. By moving the button 36outwardly, the cam actuating element 32 and button 42 will move the drycell 26 upwardly, providing an electrical contact with the button on thebottom of the lamp bulb 58 and completing the electrical circuittherefor. It should be noted that by positioning the cam actuatingelement in an off-center relationship with the dry cell that every timethe element 32 is reciprocated, the dry cell will be partially rotated,maintaining the dry cell free for vertical reciprocation and preventingcorrosion from freezing the positioning of the dry cell.

It is believed that from the foregoing a device has been provided whichwill accomplish all of the objects hereinabove set forth.

Having described the invention, new is:

1. In a lamp, the combination of a housing having a flat bottom andprovided at the top thereof with a lamp socket, a bulb positioned insaid socket, a vertically disposed tubular battery holder provided insaid housing under the socket in concentric alignment therewith, a battery rotatable and slidable vertically in said holder and including acentrally disposed upper terminal electrically engageable with said bulbwhen the battery is slid upwardly, a switch block slidable horizontallyon said bottom under the battery and having an inclined upper surface,means for sliding said switch block, a contact member flexibly andelectrically connected to said socket and positioned between said switchblock and said battery radially of the axis of the holder wherebysliding of the switch block efiects rotating and sliding movement of thebattery in the holder.

2. A portable night lamp comprising a housing having a base and providedat the top thereof with a lamp socket, a bulb in said socket, avertically disposed tubular battery holder in said housing secured atits lower end to said base under the socket and in concentric alignmenttherewith, a battery in said holder including a centrally disposed upperterminal and a flat lower face constituting its other terminal, thelower end of said holder being notched at circumferentially spacedpoints therewhat is claimed as along, an elongated switch block havingan inclined (References on following page) References Cited in the fileof this patent Number UNITED STATES PATENTS Name Date Hitzelberger Nov.21, 1916 5 Recker May 8, 1917 Ludescher Dec. 4, 1917 Dodds Aug. 13, 1918Liedtke May 12, 1925 Muramatsu Mar. 30, 1937 10 Number Number Name DateWiley Ian. 25, 1938 Graubner Mar. 28, 1939 Sullam July 3, 1945 FOREIGNPATENTS Country Date Germany June 1. 1922
